74HC138AF - Brand New TOS Signal Switches / Encoders & Decoders / Multiplexers
-
Description
The MC74HC138AF is an electronic component model, specifically a 74HC138AF, used in signal switches, encoders & decoders, and multiplexers. It is identical in pinout to the LS138 and is compatible with standard CMOS outputs and LSTTL outputs when pull-up resistors are added. The HC138AF decodes a three-bit address to one-of-eight active-low outputs. It features three chip select inputs, two active-low and one active-high, which facilitate demultiplexing, cascading, and chip-selecting functions. The demultiplexing function selects the desired device output using the address inputs, with one of the chip selects used as a data input while the others are held in their active states.
